1'0 all whom it may concern:

in Philadelphia, .ljenusylvania, have in\'ented certain Improvements in Drying :Maehines, of which the following is a speeitiea tion.

This invention relates to certain improve (1 from the power driven shaft ll, though Be it known that 1, Asnunw M. Sonia-3U- mm, a citizen of the United States. residing any suitable means may he used to drive the eonreyer.

The frame of the titlSlltg A is ma f strluetural steel and those parts which need not be removed are riveted together while the detaehalde parts are secured by bolts.

ments in the construction of machines .t'or

drying material, the material to he dried being conveyedthrough an melosed easing 1n WhlCll heated air is circulated;

l'lerett I tore, the casing of driers of this type were usually made of wood and the main object of the present invention is to make a. easing entirely of metal and to arrange the sides of g the casing that they can be readily detached 1 so that access may be had to any part of the apparatus.

A further object is to provide the casing with u non-conducting lining and to provide means for properly supporting the steam pipes used in heating the apparatus.

In the accompanying drawings,-l igurc 'l, a perspective View of my improved drier; Fig. 2, is a side view; Fig. 3, is a transverse sectional view on the line. 3-3 Fig. 2;-F,ig: 4, is a sectional plan view on Jtl1eline.4-4 Fig. 2; Fig. 5, is a. sectional compartments A and A? separated by a plan view on the line 55 Fig. 2; Fig. 6, is an enlarged view of part of Fig.1); Fig. 7, is a perspective view of the drier showing the panels removed; Fig. 8, is a. perspective view showing the uprights removed; Figs. 9 and 10, aredetached views of one of the panels; Fig. '11, is a er'speetive View of one of the eccentric han Ibolts; Fig. 12, is a perspective View of one of the pipe chairs, and Fig. .13, is a sectional view through one of the uprights.

' A is the casi-n of the drier having two Figs. 2' and .4.

ll-is the endless conveyor for carrying the material through the drier. The drier can be divided into as many compartments as desired by the use of transverse partitions. The conveyor passes-around sprocket Wheels longitudinal partition a, as illustrated in b-'b' carried by shafts mounted on suitable hearings at the ends of the machine. The sprocket wheels Z in the present instance are t riveu through-theworm and worm wheel the angle bars are used where. neeessary to stili'en the frame.

The partition (1. is part of the permanent structure, but uprights G, C as well as.

panels I.) at eaeh side of the casing are removable so that access may be had to either compartment A or i The uprights C are made of two angle bars placed side by side. as illustrated in Figs. 4: and 5 and riv eted together, while the uprights C are made of plates and angle bars 0', one angle bar being at each edge of the plate, as illustrated in Fig. 5. These uprights are de- Etachably seeured to plates a permanently secured to the upper andlower framework of the drier as shown in Fig. 8. The up rights (I are preferably lined with non-con dueling material sueh as asbestos, and a plate ineloses the lining and laps over the edges of the'i-mgle bar 1-, as clearly shown in Fig. 13.

The panels I) extend from top to bottom of the casing and overlap the angle bars forming the uprights C, C and are held in place in the present instance by eccentric clamp bolts 6 pivoted at (2. These clamp bolts can be of any form desired and by simply turnin them in a vertical position the panels Wil be released and they can be readily removed, but when the panels are placed in position .and the clamps turned as indicated in Figs. 1 and 3, then the flanges (17. of the panels w-il1 be pressed against the fixed portion of the frames by I bolts and will be held rigidly in position. I. preferably place a non-conducting filling d ineach panel d so as to prevent, as much as possible, the rad ation of heat. The panels are made .of angle bars (1 and a sheet of metal d is placed againstthe angle bars, then the lining of asbestos, or other non-conducting material (5' is placed against the plate, after which the plate (1* placed in position and bent: around one i'nember of the angle bar (Z thus confining the non-conducting material and the plate d to the angle frame d No bolts are neces sary to fasten the plate d to the frame. The roof panels J are also made detachable and are preferably lined with non-conducting material.

The uprights C are arranged at intervals and support the brackets e of the bearing E in which the fan. shafts E are mounted. In the present instance the panels alternate with the vertical meu'ibers 0, but it will be understood that this arrangement may differ in other types of driers. The fan shaft- E carries a fan E of any suitable construction, mounted in'an opening in the partition on so that when the fan shaft is driven it will cause a circulation of air through the compartments A and A The heating pipes, C are mounted on chairs I of the type illustrated in Fig. 12, these chairs are made entirely of metal and have two uprights e and a" secured to angle bars '6 the uprights support the transverse channel member 15 and are suitably braced. The upright z" is at the back of the chair nearest the partition 64 and extends above the channel member and acts to retain the pipes G in position laterally. The pipes rest directly upon the channel members The chairs are very rigid and simple in construction and when the panels and uprights are removed and the steam connections i111? coupled, the entire steam coil can be moved out from the side of the drier without having to dismantle the entire apparatus as heretofore. It will be noticed in referring to Fig. 7 that the series of steam. coils are connected to an upper manifold g to which the steam supply pipe 9 is connected, this supply pipe extends through the roof so as not to interfere with the removal of the sides.

The drip pipe 9 is connected to a longitudinal return pipe at the floor. In some instances it may only be necessary to remove the uprights C" to gain access to the coil of pipes, but if the coil is to be entirely removed, then the'uprights O as well as the uprights C should be detached.

The bearings E for the .fan shaft are so constructed that they can be readily with drawn from the shaft when the uprights C, to which they are attached, are removed, without detaching them from said u'prights as shown in Fig. 8.

I may provide one or more of the panels D with thermometer doors d, as shown, the doors'being preferably glazed so that the thermometer on the inside of the casing can be readily examined Without opening the door. I

I" preferably make the entire apparatus of steel, all the supporting members" being made of angle shapes and the panels, tops and ends of comparatively thin sheet steel lined with asbestos or other non-conducting material.

In some instances I may make the uprights l and (l' fixed parts of the ap 'mralus and not rei'novable, and this construction can be particularly used on the conveyor side of the machine, but on the steam coil side it preferable to makev both standards detachable.

I claim I 1. The combination of a drier made of metal consisting of a frmnework having removable standards on one side 'and removable panels between said standards; a longi tudinal partition in the drier and an endless conveyer on one side of the partition; heatng pipes on the other side of said partition in position to be removed through the opening provided. by the removal of the standards and panels; with means for circulating the air through both compartments of the drier.
